Step-by-step explanation:
The domain of a graph is all of the possible x values, and the range is all possible y values.
7. The graph goes on for both the x and y values, so the domain is (-inf, inf) and the range is (-inf, inf).
8. In this case, the domain is also (-inf, inf), but the range is [-2, inf) as there are no y values less than -2.
9. The domain is [-2, 2], as the x values only range from -2 to 2. The range is [-3, 3] as the y values range from -3 to 3.
10. The domain is (-inf, inf) because all x values are possible. The range is [-1, 1], as there are no y values greater than 1 or less than -1.
